Abstract

The d(e,e'p) cross section was measured at momentum transfers Q2=Q^2 = 0.8, 2.1 and 3.5 (GeV/c)2(GeV/c)^2 covering a wide range of proton kinematics at each Q2Q^2 setting that made it possible to study this reaction as a function of missing momentum as well as a function of the neutron laboratory recoil angle θnq\theta_{nq}. Missing momentum distributions were determined for fixed values of θnq\theta_{nq} up to missing momenta of 0.65 GeV/cGeV/c. For the two larger momentum transfer settings, the characteristics of the experimental momentum distributions confirm the theoretical prediction that final state interactions (FSI) contribute maximally around a θnq70\theta_{nq} \sim 70^\circ, while for θnq<45\theta_{nq} < 45^\circ FSI are significantly reduced. The data at reduced FSI settings were best reproduced by calculations using the CD-Bonn potential wave functions.
